Fobus Magazine Pouch for .40 XD?

Which model of Fobus roto double magazine pouch will hold two spare magazines for a full-sized Springfield XD in .40 S&W?

My buddy's girlfriend stumped me today. She's getting him a Fobus Roto shoulder harness for his Springfield XD this Christmas, and while she had no trouble picking the right holster, the magazine pouch recommendation to go with it specifies that it's a .45 H&K pouch. She was worried that it might not fit his .40 XD magazines.

I've tried my best to help her, but can't come up with a solid answer for her. I'm getting a little frustrated and thought maybe someone here could bail me out.
